Luis Sanchez looks set for victory in the Tour Down Under after an another impressive ride on the penultimate stage on Saturday.

The 21-year-old, in only his second professional race, was part of a break dominated by his Liberty team.
The stage - a 92-mile ride from Willunga to Willunga - was won by team-mate Alberto Contador.
Contador's victory came in what was his first competitive ride since recovering from brain surgery.
The Spaniard first discovered his health problem when he crashed
during the Tour des Asturias last season.
"I had bleeding on the brain, which made me crash
during that race," he explained.
"Fifteen days later the same thing happened again but when I was asleep. That's when they took me to the hospital, and 20 days later they operated.
"Thank God, in November they said that I was healthy so that's
when I started training harder than ever so that something like this
"I want to dedicate the stage to the team, who supported me
during the difficult times."
Sanchez now holds a 35-second lead over team-mate Allan Davis, while Stuart O'Grady is in third place, another 12 seconds back.
Britain's Bradley Wiggins had a diabolical day in the saddle, finishing almost 20 minutes behind the stage winner.
